Overview
I've been working on a project which uses the Silverlight 4 Toolkit chart control. The control is great, however there is no real zoom functionality which is a problem.
Here is an example given where the charts template is moidified to provide a ScrollViewer wrapper for the chart panel which allows you to zoom the whole chart and scroll around it:

DataVisualization -> Zoom

The big problem with this is that the axes are scrolled with the chart surface, which is not the desired effect.

Solution
I thought about this for a while and came up with a solution without modifying the source.
